FBI steps in to help stop violence

CHICAGO -- As city leaders struggle to stop the violence in Chicago, the FBI is getting involved.

The agency's director visited the windy city for the first time this week since he took over the job in the fall.

His visit comes on the heels of another violent weekend in Chicago where 37 people were shot and four were killed.

"I'm painfully aware of the loss of life in Chicago through violent crime. Not just this last weekend, but in recent months and years. Please think about ways in which we can make an additional contribution, I don't know what that might be, but if there is, I want to do that," said FBI Director James Comey.
